winmm/tests/mci.c testcase work-in-progress

The MSDN example that breaks Wine is at
http://msdn.microsoft.com/en-us/library/dd798631(VS.85).aspx
Recording with a Waveform-Audio Device

The test should create a tempfile.wav of 2 seconds exactly. If you have no
microphone (I haven't), it'll record 2 seconds of (near) silence.

                              ^^^^^^^^^
One bug in Wine is that the length of the data chunk is left as 0 because of
the switch from recording to playing.
